flanking units from Hay Force pushed the Japanese into their path. The 2/6th took over from the commandos at Ami in March and the 2/5th took over from the 2/7th in June. Around this time, the 2nd New Guinea Infantry Battalion was assigned to the 17th Brigade and undertook patrols between Hayfield and Gwalip, before the 2/7th took over. In July, they pushed towards Kiarivu, as the Australian advance moved into the mountain areas. The war ended shortly after this, in mid-August, by which time the brigade's four battalions were in action against the Japanese around Mount Irup. Following the conclusion of hostilities, by mid-October the 17th Brigade concentrated around Dallman Harbour. The demobilisation process began shortly after the war ended, with drafts of personnel being returned to Australia based on priority. A series of cross postings also occurred at this time, with 17th Brigade units swapping personnel with units from the 8th Brigade. Meanwhile, personnel undertook parades and occupation duties, overseeing the surrender of Japanese personnel. There was a shortage of shipping at the time, so the process of demobilisation was slow. The troops were kept occupied with other activities including vocational education and training, and sports. From November, Moten relinquished command of the brigade, taking over the 6th Division, while a series of administrative commanders temporarily took over the brigade. Cross postings came to an end in December, and that month the main body of the brigade began moving to Australia, with troops from the 2/5th embarking upon the troopship Duntroon, and cadres from other units embarking upon the British aircraft carrier, Implaccable, departing Wewak on 14 December 1945. After arriving at Woolloomooloo, the brigade concentrated at Wallgrove, New South Wales, before a period of leave. In January 1946, at Puckapunyal, most of the brigade's personnel were demobilised while a small cadre remained to complete the administration necessary for the brigade to be disbanded. In the post war era, the 17th Brigade was not re-raised. Its numerical designation is perpetuated, though, by a logistics formation, the 17th Sustainment Brigade, which was raised on 20 May 2006 as the 17th Combat Service Support Brigade. Units During World War I, the brigade consisted of the following units: 62nd Battalion (25 April 1917 – 16 May 1917) 63rd Battalion (25 April 1917 – 16 May 1917) 65th Battalion (17 May 1917 – 16 September 1917) 66th Battalion (25 April 1917 –
